有朋友找到我们,他们数据库启动报ORA-01092 ORA-00704 ORA-00702错，使用自研的ORA-702_Recovery Tool小工具可以实现一键恢复,下载地址：ORA-702_Recovery下载

以前有过类似恢复经历:
2019恢复第一单—ORA-704-ORA-702恢复
恶意删除bootstrap$导致数据库无法正常启动
ORA-00702: bootstrap verison ” inconsistent with version ’8.0.0.0.0′
这个问题本身相对比较简单,客户根据网上介绍,自行尝试恢复,经过客户一系列的处理之后,数据库启动报ORA-00704 ORA-00943错

因为根据最初的错误知道是bootstrap$异常,现在报该错误,应该是bootstrap$没有处理正确导致,我们通过对bootstrap$重新处理,数据库直接open成功
open

根据以前恢复经验ORA-00702: bootstrap verison ” inconsistent with version ’8.0.0.0.0′,很可能是由于bootstrap$表异常了.
通过dbv检查system文件确认没有坏块
dbv-system

通过bbed分析,确认记录被删除
把数据文件拷贝到本地,通过bbed进行分析,确认记录丢失

故障原因跟踪
有人在数据库中注入了恶意脚本，导致数据库删除了bootstrap$中数据,关闭之后无法正常启动
delete-bootstrap$

处理方法
通过oracle bbed 修复数据字典,正常启动数据库
